To all whom it may concern:

Be it known that I, HUGH DRYSDALE, a citizen of the United States,residing at Cleveland, in the county of Ouyahoga and State of Ohio, haveinvented a new and useful Animal-Clippin g Machine, of which thefollowing is a description sufficiently full, clear, and exact to enableany person skilled in the art or science to which said inventionappertains to make and use the same, reference being had to theaccompanying drawings, forming a part of this specification, in whichFigure 1 is a vertical longitudinal side view of the entire machine.Fig. 2 is a front "iew of the drop-arm; Fig. 3, a vertical section ofsaid drop-arm, taken between the dotted lines o c and b Z) of Fig. 1,showing the manner of coupling the clipping device to the drop arm anddrive-shaft, also the manner in which the clipping device swivels withrespect to the drop-arm; Fig. 4C, a front view of the rotating frame asit appears after the removal of the balance-beam and stand; Fig. 5, avertical sectional viewof the rotary handle and the mechanismimmediately connected therewith for operating the cutter and a sectionalperspective view of the clipping mechanism and tension device.

, Like letters of reference indicate corresponding parts in thedifferent figures of the drawings.

My invention relates to that class of animalclipping machines which aredesigned to be operated by the hand or by power; and it consists in anovel construction and arrangement of the parts, as is hereinafter morefully set forth and claimed, by which a more effective device of thischaracter is produced than is now in ordinary use, and the nature andoperation of the improvement will be readily understood by allconversant with such matters from the following explanation.

In the drawings, A represents the stand or body, B B 15 its legs, 0 arotary frame secured on the top of stand, and F a balancebeam sustainedin said stand and supporting the droparm I, constituting the frameworkof the machine. The beam F carries on its rear end a counterbalance L,that is rendered adj ustable thereon by means of the set-screw L. 011the forward end of same is permanently secured an L-shaped lug G, thelower portion of which is hinged to and between the bifurcated drop-armI by means of the shaft II passing through the extensions 6 e of saidarm and said lug that said arm may be swung to or from the body of themachine, as referred to hereinafter. Said beam F is secured in a bearingprovided in the arm extension D of the shaft X by means of a set-screw,as shown in Fig. 4:, the threaded portion of which enters a transverseslot or groove in the beam that prevents end motion of said beam in saidarm and permits of a rotary motion of said beam in said arm to theextent of the slot or groove in said beam, that the drop-arm Iaforementioned may be swung to the right or the left of theperpendicular thereof, and at the same time be tilted up or down on theshaft X in conjunction with the t0and-from swinging motionaforedescribed, thus giving to the drop-arm a great range of motion.WVithin the hollow of said drop-arm I is provided a shaft 01, (see Fig.3,) with suitable bearings on the boss 0 and in the socket-piece y, andis secured in place by means of the bevelgear a pinned to upper end ofshaft and resting on said boss. A slotted socket-piece is pinned to thelower end of same, that shoulders within the socket-piece y, thatprevents end play of said shaft in saidvarm, and referred tohereinafter. The socket-piece y is recessed to correspond with theshouldered end of the L-shaped lug J, and these parts are securedtogether swivel-like by means of the screws 6 c, or their equivalent,extending from the sides of said socket-piece under said shoulder insuch a manner that said lug may be readily rotated therein and by saidmeans is said lug J coupled to or uncoupled from the drop-arm I andswivels with respect thereto.

The L-shaped lugs J and P are provided with gear-pits f and f. Theircorresponding extensions are journaled, male and female, as shown inFig. 5, and are secured together by means of the shaft g',extendingthrough them, with bevel-gears a and a pinned on either end thereofwithin said pits, which prevents said lugs from separating, but permitsthem to revolve one over the other. Said lug J is provided with a shaftg, that carries on its lower end a bevel-gear a, that meshes into anddrives the gear a The upper end of said shaft extends out of the lug andis provided with a washer h, secured with a pin that prevents end playof said shaft in said lug. The outward-extending portion of said shaft 9carries a drive-pin that corresponds to the recessed and slottedsocket-piece Z, carried on the shaft d aforementioned, engages therein,and is driven thereby. Thus it is obvious that the shafts d and g arecoupled to or uncoupled from each other simultaneously with the couplingor uncoupling of the lug J to the drop-arm I aforedescribed. Ashank-piece y is formed with a journal y and a transverse vertical backan and is secured to the L- shaped lug P by means of the shaft 9extending through them, with a bevel-gear a pinned on one end, thatmeshes into and is driven by the bevel-gear a On the opposite end ispinned the disk u, that shoulders within the axial bore of the verticalback m, that prevents end play of said shank, but permits rotary motionthereof. Thus it will be seen that the shank 1 is rotated on the shaftg, revolved on the lug P and swiveled on the lug J in the socket y withrespect to the drop-arm I. A tubular handle 713 (shown in lateralsection in Fig. 10) is secured to a shoulder extension g on the verticalback m by a driving fit, and by which the cutting parts are directed onthe animal in the hand of the operator. Extending forward from the loweredge of said vertical back m are two base-blocks n n, (see Figs. 6 and11,) to the under side of which is secured by screws a comb-plate 5c ofthe usual construction, and from each end of said back or are twosimilar extending cars 01 a, one above the other,which are provided withpins 0 0, secured screw-like therein, that serve as asupporting-slideway for a drive-head z, referred to hereinafter.

The drive-head consists of a rectangularshaped block 2. A vertical Viewof the back of same is shown in Fig. 9 and a top plan view in Fig. 10,and has a downward extension 1:, transverse slideways corresponding tothe slide-pins o 0 aforementioned, a round recess 2 vertically lettherein from the top, with a mill cut or slot from the back into saidrecess, and carries a ball t and cap-piece F corresponding thereto, andreferred to hereinafter. Said drive-head z is slidably mounted on saidslide-pins independent of the vertical back on and cutter-plate s, butin suitable contact therewith, the downward extension '2) engaging withthe notch s in the cutter-plate 8, (see Fig. 8,) and the ball 25 has anopening corresponding to the crank-pin and engages thereon, as shown inFig. 11. Thus it is obvious that by rotating the disk to said head isreciprocated on said pins, and with it said cutter-plate on thecomb-plate :23, by reason of their engagement, as above described.

I make use of the round recess 2 and the ball 25 therein, for connectingthe crank-pin with the drive-head, as affording a most perfectconnection of the crank-pin and head with the least possible friction. Iseparate the drive-head from the cutter-plates, as described, that allthe knock and jar caused by the crank-pin in its circular path will beretained within said head and on said pins, so as not to interfere withthe tensioning of the cutter-plates, referred to hereinafter.

The cutter-plate s, reciprocated on the comb-plate 00, as abovedescribed, is guided in its lateral reciprocation by means of the twoguide-pins 1 extending downward from under side of presser-plate (1 (seeFig. 7), and extend through rectangular slots 5 s in the cutter-plateinto corresponding openings in the co1nb-plate, the rear edge resting onthe base-blocks 'n n, the forward edge resting on the forward edge ofthe cutterplate 8, and secured to the comb-plate as by means of thebinding-screw w and thumbnut 29. Said screw is introduced therein fromunder side of comb-plate a; and extends upward through suitable openingsprovided in all three plates 00, s, and q and part way through thethumb-nut p, it being threaded to correspond to said binding-screw. Themanipulation up or down of said nut on said screw causes thepresser-plate to clamp the cutter-plate s to the comb-plate w and createa tension of the cutter-plates more or less tight, as the tensiondesired to clip the hair may require. The tension thus required ismaintained by means of the set-screw r, having a thread corresponding tothat in said nut, and is entered from the top and forced against the endof said binding-screw, that cramps the thread of the nut in oppositedirections, thus causing a frictional lock of the nut and binding-screwthat is of sufficient strength to hold any desired tension from changingby reason of jostling or hard usage and is of such a nature as to bequickly and easily reset to any desired tension. I secure and tensionthe cutter-plates, as above described, independent of the drive-head z,in order to avoid in said knives the knock and jar that is common insaid head, to leave the cutter-plate sfree to move on the comb-platesensitively subject to its tension.

' The shaft H aforementioned, besides hinging the drop-arm I to the beamF, carries on one side of the lug G a bevel-gear a, that meshes into anddrives the bevel-gear a, and the continuous shafts cl, g, g, and g andtheir respective trains of bevel-gears, together with the disk a,drive-head z, and cutter-plate 5. On the opposite portion of said shaftH is carried the band-wheel b, that is connected by means of the belt Qto the fly-wheel R, carried on the shaft E in the frame (I. The revolving of said wheel R imparts motion to the band-wheel I), shaft 11, gear a,and the continuous line of incased shafts, drive-head, and cutter-plateaforedescribed. The shaft E also carries a pinion S, that is geared intoand is driven by the geanwheel T, carried on the shaft IV. Said shaftmay be driven by a handle O or bya belt from a power passing around thepulley N. The legs of the machine are threaded into the downwardextensions of the plate A. Upright columns U support a table-plate A,upon which is secured a corresponding base-plate V of the frame 0 bymeans of the base-bolt M, that permits the stand 0 to rotate upon thebody A in conjunction with the up-and-down rocking of the balance-beamF, and the to-and-from and the lateral swing of the drop-arm Iaforcdescribed.

The drop-arm I is calculated to furnish bearings for the shafts andtheir gears and to carry the clipping device independent of said shaftsin such a manner that they are properly united, but free from the weightthereof or the friction caused from cramp or twist in operating thedrop-arm and clipping parts over the animal. Said drop-arm also servesto shield the operator and prevent foreign substance from wrapping onsaid shafts when in motion.

Having thus described my invention, What I claim, and desire to secureby Letters Patent, is-- 1. In an animal-clipping machine, the cutter-carrier consisting of a shank-piece y, terminatin g in a back m, andformed with projecting base-blocks n n, similar extending ears n n, incombination with a comb-plate 0a, a cutter, means for operating thesame, slidepins 0 0, and a handle-case 70, substantially as set forth.

2. In an animal-clipping machine, the cutter-carrier consisting of ashank-pieccz vertical back m, formed with base-blocks n at, similarextending ears n n, slide-pins 0 o,

comb-plate x, and handle-case 7c, in combi- 5o 4. In an animal-clippingmachine the drop- 7 arm I consisting of a tubular extension Z, andformed with a socket-piece y, swiveling with respect to the swivel-arm,one end bifurcated and hinging with respect to the balance-beam F, incombination with a shaft d, incased and supported in bearings withinsaid arm independent of the swivel-arm and rotating handle,substantially as set forth.

5. The combination in an animal-clipping machine, of a drop-arm I,incasing and sup porting a shaft d, and having a socket-piece y, andmeans of engagement 6 e, with a swivelarm .I, and shaft independent ofthe shaft cl.

6. The combination in an animal-clipping machine, of a shaft d,supported and incased within a drop-arm I, and having a slottedsocket-piece Z, with a swivel-arm J, having a shaft 9, and acoupling-pin 2', engaging with said slotted socket-piece, substantiallyas set forth and for the purpose specified.

'7. In an animal-c1ipping machine, the rotating frame consisting of abase-plate V, formed with standards 0, and having bosses and bearingstherein suitable for the shafts W E and X, in combination with the shaftW, carrying a band-wheel N, gear-wheel T, a shaft E, carrying a pinionS, and grooved wheel R, a shaft X, formed with an arm extension Dsupporting the balance-beam F, in a rotary and tilting manner,substantially as set forth.

In testimony whereof I sign this specification, in the presence of twowitnesses, this 25th day of May, 1891.
